Every 60 / 48 / 36 seconds, Aeon gains a shield that blocks the next enemy spell that would hit him. If a spell is blocked this way, Aeon is suppressed for 0.5 seconds while bowing to the enemy that cast the spell and he gains one stack of Hour of Judgement.

Hour of Judgement
Passive: Aeon gains a charge of Hour of Judgement at set intervals, changing the color of his clock from no color at no stacks, blue at one stack, green at two stacks and yellow at the maximum three stacks.

Requiem of the 13th Hour
COST: 100 / 150 / 200 mana
COOLDOWN: 180 / 160 / 140
Active: Aeon marks an enemy champion channels for at least 2 seconds and up to 6.5 seconds. Activating the ability again after the first 2 seconds ends the channel early. After channeling, if the marked champion is still visible, Aeon teleports to that champion, suppresses it for 2 seconds and strikes it with one clock hand for each half second he channeled, dealing magic damage. If he channeled for the full duration, the target will be stunned after the attack ends.

Minimum Damage: 120 / 180 / 240 (+ 60% AP)
Maximum Damage: 390 / 585 / 780 (+ 195% AP)
Stun Duration: 0.5 / 1 / 1.5
The stack interval for Hour of Judgement and the shield generating time for Nullifying Barrier are not cooldowns, so they are not affected by cooldown reduction.
Due to a different attack animation, Aeon is unable to act for most of the duration of Rift Betwixt Twin Blades' knockup.
